Door handles are among the most germ-infested objects in houses, hospitals, factories, and elderly homes. We stand behind our mission to build a better and healthier world, which is why we’re sharing free design files for all worldwide to 3D print hands-free door openers. Careful analyses by our risk prevention advisors on how viruses spread confirm that by using our covered arms instead of our bare hands, we can work together to avoid further passing on COVID-19. Let's work together to stop the spread!
To maximize part strength and minimize the support needed, we recommend printing the parts on their side. In our test prints we found that printing according to the orientation shown in the following image is the most effective and efficient way.
To prevent the opener from rotating, we suggest placing an elastic band between the handle and plastic. Please note that small rubber sheets are included in the i.materialise orders.
Tighten the screws enough to ensure that the opener stays in place, and adjust the longer screws to fit your door handles.
For more tips and tricks, please watch our video.
We also designed a sticker to be placed on doors with the openers. This sticker shows a basic illustration of how the device should be used along with the rationale that it is there to prevent people from spreading germs.
